Summary Introduction
To analyze:
The factors that are contributing to the current extinction crisis.
Introduction:
Species is declared extinct if there is no surviving member of that particular species.
Extinction crisis: According to current extinction rate each year about 0.01% to 0.1% of all species will be extinct. This extinction crisis is mainly anthropogenic.
